The 1870 discovery of zinc ore near Galena, Kansas, marked the beginning of a century of lead and zinc mining in the Kansas part of the Tri-State mining district (fig. 1). The Tri-State was one of the major lead and zinc mining areas in the world and included parts of southeastern Kansas, southwestern Missouri, and northeastern Oklahoma.

By 1845 Galena was producing nearly 27,000 tons of lead ore and Jo Daviess County was producing 80 percent of the lead in the United States. Wisconsin lead mining peaked in the 1840s. In 1844, a third of the region's residents left for copper and iron mines elsewhere and the discovery of gold in California caused many others to head west in 1849.

Galena often contains silver, zinc, copper, cadmium, bismuth, arsenic, and antimony; in fact, the value of the silver content often exceeds that of the lead, in which case it is deemed a silver ore. Other commercially significant lead-containing minerals are cerussite (lead carbonate)…

By that time, Galena boasted three banks, three newspapers, and an opera house. Though its primary lead and zinc mining and smelting remained its principal industries, there were also foundries, stamping works, grain elevators, novelty works, and a broom factory. The population in 1910 was 6,096.

A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue. Forms of Lead and Zinc Ore The two principal minerals containing lead and zinc are galena and ...

Flotation separation and recovery of lead and zinc concentrates from ores containing galena (PbS) and sphalerite (ZnS) is well established and generally achieved quite effectively. Silver often provides highly significant economic value, if not the greatest value, with the silver most often associated with the galena mineralization which is ...

Lead is a naturally occurring metallic element usually associated with other ore minerals (primarily those of zinc, silver and copper) such as pyrite, sphalerite, quartz and barite.Trace amounts of other elements including gold are sometimes found with lead ore. The most common ore mineral of lead mined in the United States is galena with the chemical symbol PbS.

Galena also was a major mineral of the zinc -lead mines of the tri-state district around Joplin in southwestern Missouri and the adjoining areas of Kansas and Oklahoma. Galena is also an important ore mineral in the silver mining regions of Colorado, Idaho, Utah and Montana.

This includes lead concentrate and refined market lead (99.97% and 99.99%), as well as lead-antimony alloys, copperised-lead alloys, calcium lead alloys and calcium tin-lead alloys. Lead concentrate is essentially a mineral called galena, which predominantly contains lead and sulphur. Smelting converts this into a metallic lead form.
